Dream Echo

Speaking in a series of self echos, this spell can only be cast while on the plane of dreams. 

When on the plane of dreams, this spell can allow the caster to see the echos of all the creatures/beings that have passed through an area within 20feet of where the caster stands.

These echos will show the faint outline of the shape of the entity that moved through the area.  If an entity was moving during the duration of the spell, a series of translucent flashes will show the path taken. 

If the caster moves, the area of effect of the spell follows.
